How to select previous month and use it to calculate the sales of last month

[gluizqueiroz]

I have the following table:

CodSale	Sold	Date
1	125	2018-05-10
2	100	2018-05-15
3	150	2018-05-20
4	50	2018-06-20
5	75	2018-06-25

I need to make a measure that returns me the following table:

Month	SoldLastMonth
May	0
Jun	375 (Sum of sales May)
Ago	125 (Sum of sales Jun)

I tried to use PREVIOUSMONTH and EDATE(Date; -1) but doesn't work.
I will use this measure on a graph to see "Month Over Month".

hi @gluizqueiroz

in order to be able to use TIME INTELLIGENCE functions, you need to create a date dimension and link it to the fact tables:

Hi @gluizqueiroz

Have you got a Date table? Time intelligence functions are only guaranteed to work if you have a "complete" Date table.

If you don't, create one, place Month in rows of a matrix visual and this measure in values for the previous month sales:

SoldPreviousMonth =
CALCULATE ( SUM ( CodSales[Sold] ); PREVIOUSMONTH ( CalendarTable[Date] ) )
